The Lions have signed free agent defensive tackles Ego Ferguson and Bruce Gaston, the team announced. To make room on the roster, the Lions waived defensive tackles Nick James and Maurice Swain.

Ferguson has now signed contracts with three of the NFC North’s four teams this offseason. After being cut by the Bears in April, Ferguson’s deal with the Packers was scuttled when he could not pass a physical. Apparently, he was healthy enough this week to sign a deal with Detroit. If he doesn’t make the Lions’ 53-man roster, perhaps he can try his luck with the Vikings.

Ferguson, 26 in September, appeared in all 16 games during his rookie campaign with the Bears in 2014, but ailments have limited him to just four games since then. The Raiders auditioned him after the Packers deal fell through, but the Lions are the only other team we’ve heard linked to him in the last two months. As Justin Rogers of The Detroit News (on Twitter) notes, Lions fans may remember Ferguson from a 2014 incident in which Lions center Dominic Raiola stepped on Ferguson’s leg. That dirty play resulted in a one-game suspension for Raiola.

Gaston, another former Bear, appeared in seven games for Chicago in 2015. Last year, he was with the Panthers’ practice squad. Gaston had shoulder surgery in 2016, but he has likely recovered by now.

As far as draft picks go, Northern Illinois wide receiver Kenny Golladayis the only player that has yet to put pen to paper. The reason for the delay is not known, but third round picks often take longer to sign than other picks as things are less rigid in those slots.

Davis was said to be a target of the Dolphins at No. 22, so it’s a good thing that the Lions were up at No. 21. Davis impressed scouts at his Pro Day when he posted a 4.56 40-yard dash and 38.5 inch vertical jump. As shown on Roster Resource, Davis may be in for a starting role in 2017.

Kaaya was said to have one of the highest football IQs of any quarterback in this year’s class. It remains to be seen whether he has the arm to make it as an NFL quarterback, but the Lions believe that he can be a solid backup QB, at minimum.

According to Tom Pelissero of USA Today (on Twitter), Valoaga got $22K guaranteed ($12K bonus, $10K base) to sign with Detroit. Typically, UDFAs get around $5K, so that’s a sign that Valoaga had at least a few teams interested in adding him to the 90-man roster.
